Sounds like the kind of device designed to meet the regs.  In my opinion, the chirper should chirp at 100 chirps per mR.  It should NOT have an alarm - it is its own alarm! It should be durable, simple, reliable, not saturate, use a 9V common battery, have no   LCD screens, accumulate no dose numbers,... just chirp.  It should have a nylon case, not metal.  It should be inexpensive because it is simple.  It should chirp at 3000 cps which can almost always be heard in noisy environments.  It should be smaller than a pack of cigaretts and have a simple belt clip.  That's all...
